My son told his brother he had caught a mouse in a trap,and sent a pic. His brother showed his 10yo daughter, my grandaughter, and she now hates her uncle for 'murdering that little mouse'

I dare not tell her we have now caught/trapped 12 mice and voles in our polytunnel

She'll realise why the first time a mouse eats her Easter egg or whatever. (It's not as if she won't eat the lovely little black lambs we have

)
Don't let it get to you - they asked; you answered.
